If it is planned to make a fence of corrugated board, it is necessary to make a calculation of materials (sheet, supports, fasteners). To simplify the task, a scheme of the future design is drawn up taking into account the length of the gate (swinging, sliding) and the gate.
In the case when the work is planned to be carried out by oneself, the outline of the fence, the calculation of materials, the preparation and installation - everything will have to be taken over. If you turn to professionals, the total cost will be the drafting and installation work.
What is included in the calculation
First you need to determine if there is a serious slope of the terrain. In this case, the height difference of the profiled sheet is made. Then more material will be needed (some of the supports will be higher).
The calculation is based on the design features: the type of pillars / supports, the width between them, the length of the lag used for fixing the profiled sheet, the method of mounting the gate (swinging, sliding), the foundation and its characteristics, and the number of profiled flooring.
The fence scheme and its calculation example
In short, to calculate the material, you need to take into account the device of the fence from the corrugated board. Plus, a small stock is added. Fixing elements (self-tapping screws), through which the profiled sheet is mounted, are taken from the calculation of 5-7 pieces / sheet depending on the number of cross-pieces. The recommended type of material used is the wall type (grade C). You can choose a galvanized version of the profiled sheet or with a polymer coating.
Choosing a fencing structure
Drawings fences are made at the initial stage, which greatly simplifies the installation and allows you to build a reliable design. The location of the profiled sheet relative to the ground may be different: a recessed or raised installation. If the ribbon variant of the foundation is chosen, in this case also the gap between the base and the corrugated board is different.
It differs also in the type of racks: brick with reinforcement in the form of a metal pipe of circular cross-section; profiled pipes of square (60x60 mm) or rectangular (40x60 mm) configuration. Calculation of the material is also based on how the lags are fastened: inlay, butt. This also determines the distance between the neighboring posts.
In the first case, the double width of the profiled sheet is optimal, and the useful width is taken into account. If the frame is mounted butt-end, the maximum distance between the posts is 3 m. The profiled material can be positioned vertically and horizontally. In addition, the design of the fence can be continuous and with lumens for the pillars.
Common brands and sizes of proflist
Common dimensions of the profiled sheet: height 2 m, full and useful (working) width depends on which brand of the product is selected. If the fence and installation work are done by yourself, you need to ensure the maximum reliability of the structure.
The most common grades of profiled material for the price-quality ratio are: C8, C10, C18, C20, C21. In the designation, the height of the undulating profiled profile is ciphered, respectively, 8, 10, 18, 20, 21 mm. The thickness of the material should not be less than 0.5 mm.
Horizontal mounting of corrugated board with gaps
To calculate the amount of material in this case, you need to take into account that the width of one product during installation is simultaneously the height of the fence. The distance between the pillars is decisive. The length of the profiled sheet should be approximately equal to the value of this parameter. When calculating the material, it is necessary to subtract 10-20 mm, which is caused by possible roughnesses of the racks.
If the sheet is horizontally positioned, a solid installation can be made. Then at the junction of prof-products a small overlap is taken into account, equal to the sum of half the width of one rack and 10-15 mm.
Vertical installation without lumens for poles
In this case, the fence scheme is a continuous sheet without the slightest gaps between the sheets. Racks are hidden behind the corrugated board. To calculate the number of columns, you need to determine the working width of the profiled product. Important nuance - all connections must fall on the racks. This will provide increased reliability of the structure.
With continuous installation, the span between the columns corresponds to the total working width of the sheets, from this value it is necessary to subtract the width of one column. Such a calculation is made for fencing, the span of which is two sheets.
The scheme of the fence of a continuous sheet without the slightest gaps
If we consider the situation when there are three units of profiled products between the two racks, then the amount of material can be calculated in the following way: the useful width of three sheets is added, the width of two columns is subtracted from the obtained value.
Calculation of the total number of sheets for this case: from the perimeter value, the numerical value of the width of all columns is subtracted (their number is multiplied by the width of one rack), then the result is divided by the distance between the supports and multiplied by the number of profiled products in each span. And a reliable calculation implies a deduction of the width of the gate (swinging, sliding) and the gate, if it is located side by side.
Base for fence from profiled material
Different types of foundations for pillars
Therefore, more often an approximate calculation. In this case, it is recommended to select the base of the tape-columnar type. Such a solution ensures a uniform distribution of the load exerted on the fence when punching the soil.
The main feature of this type of foundation is the determination of the depth of the pillars, while the belt base can be buried to 0.5 m below the soil surface. To calculate the depth of the pillars, you need to determine the level of load exerted by the wind and per unit of the rack.
This parameter is calculated on the basis of the area of the profiled sheeting, the aerodynamic coefficient for vertically disposed flat surfaces (equal to 1.4), and the index of high-speed wind pressure.
The value of the torsional moment is also determined. When it is divided by the resistance moment factor (equal to 225), you can find out the depth of the foundation under the fence poles.
In order to determine how deep the pillars should be laid, it is allowed to use the soil characteristics, in particular, the depth of freezing. For different regions this value can be different. When preparing a trench under the foundation, in particular, holes for the pillars, you can not allow the stand to go beyond the sand cushions located under the concrete base. This will accelerate the corrosion of metal.
Thus, all calculations (amount of material, foundation) should be performed only after the scheme of the future fence has been drawn up. When calculating the number of profiled sheets, you need to subtract the length of the gate (swinging, sliding) and the gate from the perimeter.
All the actions can be done by oneself, the only difficulty is the calculation of the foundation of the fence. When the design of a fencing is thought over, it is necessary to protect as much as possible the bottom part of a professional flooring from damages under the influence of a dust, dirt.
In order to correctly calculate the fence, first you need to make a markup of the enclosed territory. For this, each side of the perimeter is measured. Then, having combined the length of each side, we obtain the total length of the entire fence. The number of sheets of corrugated board is calculated using the following formula:
- n is the quantity;
- L is the total length of the barrier;
- b is the width of one sheet.
If the width of the territory is 20 m and the length is 40 m, the total length of the fence will be 120 meters. The sheet has a width of 1.4 m.
They must be overlapped.
Therefore, discarding 10 cm from each side, take a width of 1.2 m. Substituting the numbers in the formula, we get:
- 120 / 1,2 = 100 sheets.
It is this much profiled sheet that is necessary to completely cover the entire perimeter. The height of the sheet is 2 m. The height of the profile (the ridge) is 0.7 mm. Mount them best on a profile pipe 4 × 6 mm, which has a wall thickness of 2 mm. Pipes are installed at a distance of 2 meters from each other. For each of them, a pit is dug 30-40 cm deep. The pipe is inserted into the pit, around it concrete is poured. That its plane, which has 6 mm, must be fixed parallel to the perimeter line. Pipes are used as support pillars. Their height should coincide with the height of the corrugated board.
Fence installation from profile sheets
After the support poles have been installed, they are welded to the transverse profile pipes. Profiled sheeting is attached to them with the help of self-tapping screws. Self-tapping presses corrugated board. To keep the sheets firmly, it is necessary that one side is screwed with at least three screws.
Profiled sheeting on the fence is made in such a way that from the transverse lag to the edges of the profiled sheet there is not more than 20 cm. In this case, the sheets will have sufficient rigidity, able to withstand a strong gust of wind. This measurement should be made necessarily. If you need to calculate the corrugated board at a cost, you need to take into account its coverage. Simple galvanized corrugated sheet is the cheapest, having a polymer color coating is 40% more expensive.
When installing support poles and transverse logs, it is necessary to use the building level. Using the level, all parts must be installed in a strictly vertical and strictly horizontal position. There should be no slopes and distortions. This will ensure the construction of greater strength, improve its appearance.
To build a fence of corrugated board, you need a tool like:
- Welding machine.
- Bulgarian.
- Electric drill.
- Building level.
- Shovel.
To provide the tool with electric power to the work site, it is necessary to stretch 220 V carrying. The fencing from the profiled sheet is strong enough and durable. Due to the fact that the zinc-coated material is not susceptible to corrosion, it can last for more than forty years. The painted barrier has a strict and solid appearance.
In order to deliver excellent, strong and attractive, it is necessary to correctly calculate the amount of material that will be needed during the work. This will depend on the reliability of the fence, the time spent on the entire construction process, and the financial costs of delivery, preparatory work, installation of the fence.
In this article we will consider which factors affect the calculation of components for fencing, what can be the cost of such a structure.
Calculation factors: we construct a new fence
To calculate the profiled sheet needed for future construction and other components, it is necessary to take into account certain factors without fail. Always remember that any enclosure is an individual design even when using standard materials.
But even with the simplest forms, the fence will consist not only of a profiled sheet, but also of supporting poles and cement for pouring the support, transverse rows (logs that give the structure additional strength and rigidity). Such constructions are impossible without a gate or a small gate.
For fencing is used with a wave height of ten to twenty millimeters, which can be a simple galvanized (the cheapest option) or with a polymer colored coating on one or two sides (the cost rises by about forty percent).
Support pillars are made from a square shaped pipe, the cross-section of which depends on the height of the fence.
Profiled sheeting allows you to make fences up to eight meters high, which does not affect the strength. Needed and lags, the number of which can be different and which will be attached to the corrugated board, fasteners: self-tapping screws and steel rivets for joints.
How much does the fence of the profiled sheet cost?
So, how much can the fencing of the corrugated board cost? First of all, it is necessary to take into account the length of the future fence, height, type of construction (with foundation, without foundation, combined options).
The main elements from which the financial costs will be formed:
- , which can be simple galvanized or with a polymer coating. The best is PS-10, PS-20.
- Lags (cross-pieces). Economy option - logs made of wood, the most durable - from the profile pipe. The number of logs or rows depends on the height of the structure.
- The foundation under the pillars (you can not do, but with the foundation will be more reliable).
For example, we calculate the material for the fence with a height of two meters and a length of thirty linear meters. In order to correctly calculate the number of components, we need to decide on the design of the fence itself. In this case it will be a simple fence with supporting poles, which will be cemented in pits.
Now we need to calculate the number of pipes for the pillars, we take a pipe with a cross section of twenty to forty millimeters. We need thirteen pillars of two meters eighty centimeters, that is 36.4 m ephemeral. It is calculated in this way: the length of the future fence (thirty linear meters) is divided into the length of one span (two and a half meters).
We get the value of twelve spans, that is, we need a column for one more - thirteen pieces.
When buying the best, immediately ask the seller to cut the poles, which will reduce the cost of delivery and eliminate the need for self-cutting pipes on the site (that is, we will not need some tools).
For logs (crossbars) it is best to take a profile pipe with a cross section of twenty to twenty millimeters. We will need three rows of logs (since the height of the fence is two meters). The total amount is calculated thus: thirty running meters (length of the fence) multiplied by three (the number of rows) and we get the number of logs - ninety meters of material.
For fixing the pillars we will need two bags of cement, sand and gravel. For fastening the corrugated board - roofing screws at the rate of up to eight pieces per square meter.
Now calculate the total cost using a conventional calculator:
- profiled on the fence - about 14 450 rubles;
- profile pipe for cross-bars - up to 4800 rubles;
- pipe for supporting poles - up to 2 590 rubles;
- cement, sand, gravel - from 800 rubles;
- self-tapping screws, the cost of which can be different.
The cost of delivery of the order will depend on the mileage and the person who performs it (seller or buyer).
As we can see, the calculation of the products under can be done using the usual calculator: no complicated formulas and calculations are carried out here. But when carrying out the calculations, all the factors mentioned above should be taken into account, which will help make this process more accurate.
The roll material for fences is measured by the linear value
To determine how much repair or construction work and materials will cost, it is usually not a classic meter, but a unit called a running meter. It is used in the manufacture of various types of products, when buying furniture. Most often, this indicator is used in the construction of new objects, including the meter of the fence. This is required to calculate the amount of material required for future fencing.
What is the difference between the meter concepts
With the help of the running value, measure what can be rolled up. It implies only the length of the product, and its width is not taken into account. With its help, calculation is facilitated, the cost of production decreases. After all, often the width of the building material is a standard value, and sometimes it makes no sense to pay attention to it.
This value also consists of 100 cm. In the word "running" it directly indicates that only length is taken into account. After all, "drive" means to unfold in one direction, strictly in a straight line. You can imagine that the material itself, rolled up into a roll, is just a straight line.
On the packaging rolls of many building materials, you can see the price tag, where it is written how much is a linear value. But there are those who have a price for a certain area. In this case, not only the length, but also the width of the product is taken into account. The area, equal to 1 m 2, has a square section with the dimensions of each side - 1 m.
To calculate the area of a rectangular plot or raw material for construction, the length must be multiplied by the width. The result is the area expressed in m 2. Linear and square meters have only one similarity. This length is 100 cm. In all other respects they are different.
The linear method can not measure the area, it is intended only for measuring the length. But it can easily be converted to a square meter, if the width of the product is known, which for the calculation must be multiplied with meters.
Linear value for fences
This value is a traditional fence, the canvas of which is a profile sheet or a tree. It will be equal to a simple meter if the height of one sheet is also equal to 1 m. Just as in calculating the amount of the roll material, width is not taken into account, since it is standard, the height is not taken into account when erecting a fence. It must also be permanent. But it should be borne in mind that the height of the fence does not always coincide with the dimensions of the sheets of building material.
If, for example, a fence is built with a meter in height, and profiled with a height of 1 m are used, the linear value of the fence will be equal to a meter of building material. But if the fence is higher, and the profiled sheets or boards will be used the same, they will need more. Therefore, before buying the raw materials should be properly calculated.
Calculations
Such a simple construction, like a fence around the site, requires calculation accuracy like any other object.
Attention! Competently and according to all the rules, the completed construction schemes together with all the required calculations will help to avoid installation errors and operational problems.
The enclosure consists of several elements:
- the basic framework. This role is performed by the racks, mounted in the foundation. They carry the main burden;
- spans. As a rule, profile sheets, wooden slats, mesh and concrete are used for them;
- stiffeners;
- fasteners.
To avoid unnecessary financial costs, you need to make simple measurements and calculations, how much will the material cost, using simple mathematical techniques. If the length of the fence is divided by the width of the building material, which is used as a canvas, the result will be a number corresponding to the required number of sheets.
Examples
Suppose that the enclosed area has the shape of a rectangle with sides of 30 m and 20 m. First of all, we determine how much the perimeter will be. And it will be equal to the length of the fence. For this, the lengths of the sides are added and multiplied by 2. The perimeter of this section will be equal to 100 m.
For further calculations, it is sufficient to know the width of the raw materials used and the height of the fence. For example, it will be equal to 1 m, and the raw material will be profiled. As a result, you will need to buy 100 sheets. But just in case, it's better to buy a little more to have a stock.
If the width is about 2 m, a minimum of 50 sheets is required. That is, to determine how many sheets you need, you need to divide the perimeter into the width of the material. In order to determine how many meters of material it takes to erect a fence, the perimeter is multiplied by the expected height.
That is, to install a meter fence along a 100-meter perimeter, 100 linear dimensions of building material will be required. To erect a two-meter height fence, 200 m of the same building material will be needed, and so on.
If the price of one linear quantity is known, it is not difficult to calculate how much construction material necessary for the installation of the fence will cost.
In the course of planning and drawing up an estimate for the construction of one of the tasks is the calculation of the cost of fence from the corrugated board. And although in most cases, the supplier companies provide rough calculation schemes, it is worthwhile to figure out how this can be done without outside help.
Completion of fences made from corrugated board
Main advantages
Profiled sheet metal is one of the most popular materials for the construction of roofing and enclosing structures. Due to its low cost and ease of installation, it enjoys a stable demand, and therefore metal fences of continuous type appear more often.
Other advantages of the proflista include:
- Excellent performance characteristics - resistance to moisture, sun, mechanical damage.
- Presentable external (especially in bilateral varieties).
- Long service life, which with proper care is more than 20 years. At the same time, the fence is completely repairable, and the damaged sheet can simply be replaced with the same one.
- Possibility of re-installation and re-operation. As soon as the need for the fence disappears - the sheets can be dismantled with their own hands and installed in a new location. Moreover, the instruction for installing such a fence is quite accessible for independent development.
Varieties of material
Considering all the above-mentioned advantages, the calculation of the corrugated board for the fence should start with the choice of the type of material. In this article, we will not go into the nuances of the nomenclature, such as the thickness of the metal or the number of waves, but focus on determining the main varieties.
Note!
For permanent hedges, a wall profiled sheet is used that has a higher bearing capacity. The temporary fence can also be made from a roofing sheet, the price of which is slightly lower.
The main types of steel sheet used for making fences are:
- Galvanized. Its basis is a sheet of steel 0.4-0.5 mm thick, coated with zinc passivation, which protects steel from corrosion.
From "galvanizing" fences are made for construction sites, outbuildings, etc. Since the appearance of the material leaves much to be desired, in private construction it is most often not used. - Unilateral. The material of this version on the steel base on one side is coated with a protective coating of the process polymer, and the second side is treated with a zinc layer.
Polymer coating is made in color, which has a positive effect on the aesthetic characteristics of the fence. In most cases, the basic calculation of the fence from the corrugated board is carried out on the basis of one-sided material. - Bilateral. The most expensive variety. Polymer is applied not only to the outer, but also to the wrong side of the sheet, because the fence will look quite attractive both from the outside and from the inside.
In addition, the coating is more reliable than galvanizing, protects the steel from external adverse effects, because this fence lasts much longer.
Another type, worthy of mention, is a material with a decorative surface. An example of such a profiled sheet can be the products of the Korean manufacturer PrinTech: a multilayer coating that is applied to a steel sheet, imitates the texture and color of the tree (see in more detail about), stone or brickwork. But if you try to count the fence from the corrugated board of this brand - the price can be unpleasantly surprised!
The easiest way is to calculate the materials for the fence from the corrugated board using special calculators. These programs are placed on the websites of manufacturers of profiled and assembly organizations, and therefore their functionality is significantly different.
An example of the interface of such a calculator is shown in the photo. Understand his work is quite simple, but it is still necessary to understand the cost of the erection.
If you paint the main materials in sufficient detail, we will need:
- The corrugated board itself (the number of sheets with a height of 1.5 to 3 m) needed to form the perimeter of the required length.
- Poles for the frame (both round and profiled pipes can be used).
- Material for fastening the supports (concrete or reinforced concrete for a strip foundation).
- Lags (profile tubes that are mounted between vertical supports).
- Fastening elements (special screws for corrugated board).
To additional elements, expensive construction, you can include gate systems, end plates, installed on the top of the fence, non-standard color coating, etc.
Planning of installation works
When we plan fences from corrugated board - the cost calculation should include not only the cost of purchasing materials, but also the price of the work. This moment is especially important in the event that we do not produce the assembly ourselves, but trust its professionals.
Advice!
In principle, nothing particularly complicated in the installation work is not - and you can be sure of this by watching the video on our website.
But if you have not worked with such material before, it's better not to take any chances.
- Dismantling the old hedge (with or without preserving the integrity of the materials).
- Drilling holes for supports or pouring a strip foundation.
- Installation of supports and their concreting.
- Welding of horizontal logs to posts.
- Lining the log with a profiled sheet using rivets or self-tapping screws.
- Installation of gate structures, installation of additional elements.
Naturally, all these works must be paid for. The total cost depends primarily on the dimensions of your fence: the higher it is, the higher the laboriousness.
We hope that now you have an idea of how to calculate the fence from the corrugated board, and if necessary, you can do it even without using an online calculator.
